mop handle. The'pivotal connection'between the handleand mop head, desired for the purpose not g-iying eiiective mopping strokes 43110113 the floor,- prevents the mop from being projected-forwardly. into corners and other difficultsurfaces and "the. desired accurate resultsare thus not ob-- .atained.

. {Amobiect of the inventionis to provide a-rnop which overcomes the above. disadvantages while .atQtl-re same time nab1ing-.the :mophandleto 'swing' readily with respect to the mop head. Yet

another object is to provide a mop structure wherein the mop head is held in a desired yielding relation to the handle, permitting the head to be projected accurately at any desired point while at the same time enabling the head to swing relatively to the handle as the head is moved along the floor surfaces. Yet another object is to provide a mop structure having a head which may be manipulated manually upon a pivot carried by the handle and wherein the handle is urged toward a predetermined position with respect to the head. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in preferredembodiments, by the accompanying drawings, in which Figure 1 is a perspective view of a mop structure embodying my invention; Fig. 2, a longitudinal sectional view, the handle staff having been removed; Fig. 3, a detail sectional view, the section being taken as indicated at line 33 of Fig. 2; Fig. 4, a detail sectional view, the section being taken as indicated at line 44 of Fig. 2; Fig. 5, a transverse detail sectional view, the section being taken as indicated at line 5-5 of Fig. 2.

In the illustration given in Figs. 1 to 5 inclusive, l0 designates a mop head frame formed of metal, generally heart-shape in contour and with a rear portion bent inwardly and forwardly to form a handle attachment portion I l.

A handle fitting I2 is provided with a screwthreaded socket portion l3 adapted to receive the end of the handle member M. The lower end is brought together to form a flattened portion [5 received between the handle attachment loop members II and pivotally secured thereto by rivet l6, as shown more clearly in Fig. 4.

The spring, after being looped about each end of the bolt 23, has a U-shaped portion 26 extending rearwardly and engaging the handle-receiving attachment I 2. of the U-shaped portion 26 is provided with a curved saddle 21 resting upon the tubular portion of the member l2.

The spring 24 may be formed of steel or any other suitable material, and is preferably of such strength as to cause the mop head to assume the aligned position shown in Fig. 1, when the mop head is lifted. The spring, however, flexes readily when the mop head is brought downwardly upon the floor, as illustrated in Fig. 2.

Operation In the operation of the structure shown in Figs. 1 to 5 inclusive, the mop head may be raised from the floor and, under the influence of spring 24, the head assumes the position shown in Fig. 1, with the head in substantial alignment with the handle I l. The spring not only maintains the position described, but also serves to lock the head against tilting and maintains it accurately upon the end of the handle. It may thus be projected into a corner or into any narrow surface and brought downwardly upon the floor in the selected position. The handle may then be swung rearwardly,,with the spring flexing, as shown in Fig. 2. In the latter position, the spring tends to urge the mop head firmly against the floor at its forward side.and an effective cleaning of the corner or other difficult area is accomplished. When the mop head is raised during the cleaning operation, instead of having the head tilt at awkward angles upon the handle, the spring brings it always to the same position and enables the mop to be handled as though there were no pivotal connection between the handle Preferably, the upper end has a better control of the mop head at all times, ,i

and even after periods of use when ordinarily mop heads become loose, the present mop head main tains its accurate alignment upon the handle.

While in the foregoing specification, I have set out the details of specific structures embodying my invention, it will be understood that such embodiments are illustrative and that those skilled in the art may readily modify such details without departing from the spirit of m invention;

I claim: y 1.- In a mop structure, a relatively rigid mop head having a central raised portion provided with a longitudinal slot, a handl socket having v its forward end received within said socketand having a cam surface inclined downwardly towards said forward end, a pin pivotally connecting said socket within said slot, and a second pin extending through said slottedraised portion forward of said first pin, and a U-shaped spring having central portion wrapped about said second mentioned pin and having a forwardly extending portion engaging said mop head and a 2. In a shaker mop structure, a relatively rigid mop head provided with a longitudinal slot and having a vertically extending flange about said slot, a handle socket having a tubular handlereceiving portion and a forwardly extending flat portion received within said slot, the upper portion of said forwardly extending portion providing a cam surface inclined downwardly toward said forward end, a pin extending through said flange and pivotally securing the forward end'of said handlesocket within said slot, and a second pin extending through said flange forward of said firstpin, and a U-shaped spring having its cen- 7 tral portion wrapped about said second menrearwardly extending saddle portion resting upon 7 the cam surface of. said handle socket.

'tioned pin on each side of said slot and having a forwardly extending portion engaging said mop head and a rearwardly extending saddle portion resting upon the cam surface of said handle socket. Y I
